Various devices have attempted to isolate the radiator from movement of the vehicle chassis frame during vehicle operation. For example, U.S. Pat. No. 3,638,749, to Graham et al., teaches mounting the radiator in a subframe to allow relative movement between the subframe and the chassis frame through the use of coil springs and links with rubber bushings. U.S. Pat. No. 2,071,328, to Broulhiet, teaches coupling a subframe supporting the radiator, lights, and fenders to the vehicle frame aft of the front axle in order to minimize the bending caused by up and down motion imparted on the frame as a result of vertical movement of the front wheels. However, the prior art fails to disclose a support apparatus coupled near its lower center to a support member connecting the chassis frame rails, where the support apparatus integrates relative motion of the hood and radiator in such a manner as to isolate the radiator from twisting and deflection of the frame, simultaneously allowing designers to reduce radiator to hood clearance without decreasing the fatigue life of the radiator. This is particularly important for the design of modern trucks which have the hood closely contoured to the radiator for improved aerodynamics and road visibility.
